A li ation fil d November 23, 1.906. Serial lio- 344,'763.

- To all whom/ it may concern: ,Be it known that I, W ILBUR H. THOMP- providea device 'of the aforesaid class that avoid the "aforesaid irregularities and discircuit.

SON, a citizen of the United States, and aresident of Wilkinsbur in the county of Allegheny and State 0 Pennsylvania, have invented'a new'and useful Im ovementin Electrical .A paratus, ofwhicli the following is a speci cation. 1

My invention .r'el' tes to alternating current transformers, and' it has for its object to shall be adapted to-supply energy to two or more translating devices at'least one of; which is relatively sensitive to electro magnetic disturbances Heretofore when several translating vde vices have been supglied with energ from a single transformer t eywere usual y either connected to a-single secondary winding or severally connected to independent second ary windings which were interlinked by the same magnetic flux. If the operation of one or more devices so connected is intermittent or such'that electro-Inagnetic disturbances obtain in the'transformer,- it is observed thatthe operationvof the otherrnore sensitive translating devices is irregular.

According to my lnvention, I entlrely turbances by providing-independent magnetizable cores which are ener ized by a;

t of which single primal -Win ding and sec may be provi ed with one or more secondary windings. Q a

Figures 1 and 2 of. the accompanying drawings, are, respectively, a front view and a sectional elevation of a. transformer constructed in accordance with my invention, and Fig, 3 is adiagrammatic view of asystem of distribution embodying my invention.

j Referring to the drawings, alternating current electric energy may be supplied from any-convenient "source, such as the generator 1, to a plurality of translating devices 2, through a distributing circuit 3-4.

if the energy supplied tothe translating de vices exceeds a predetermined amount, an automatlc 01170111t=-br15ak6r 5', comprising brid ing' contact members 6 and 7 and an over oad release magnet 8, will interrupt the i i-transformer 9 of special construction,

comprising a 'primary .coil 10 independent I magnetizable core members 11 and 12 and secondary coils 13 and 14, is connected in the interrupted line 4. j The release magnet 8 of the Gircuitinterrupter, 5 is provided with I is illustrated in connection with a circuit in-' terrupterand a measuring instrument two independent core members being pmfided for this purpose, its use is not restricted thereto and it will be readilyunderstood that a greater number of independent core members having one or more secondary coils may be employed within the scope of my ini vention.

I claim as my invention;

1. A transformer comprising a primary coil, a plurality of independent core members and secondary windings that'are severally infiuenced by said core members. i

2. A transformer comprising a main coil, a

plurality of secondary coils, and independent 'mag'netizable core members whereby the secondary coils are severally and magnetic ally interlinked with the main coil.

3. The combination with an electric cir cuit, a primary coil connected in series therewith, a plurality of independent cores which are magnetized by saidcoil, of a plurality of secondary windingswhich are magnetically interlinked with the primary coil by the independent cores. A .4. The combination with an electric! circuit, an interrupter therefor and a trans former coil cmnected in series therewith, of

independent magnetizable cores surrounding said coil, secondary coils magnetically interlinked by said series coil, meansfor actuating the interrupter, saidmeans being ener ize from one of said secondary coils, an another; electrical apparatus which is relatively sensitive to electromagnetic disturbances and is connected to another of said secondary coils.

5. The combination with an electric circuit, an automatic interrupter, and an electrical measuring instrument, of a trans iornier comprising a prin'iary coil connected in series with said circuit, a pair of independent core members, and secondary coils severally influenced thereby, sai l automatic interrupter belng energized irom one of the secondary coils and the measuring instrument being-energized l 'IOID the other secondary 1o coil. 7 c

i In testimony whereof, I have hereunto subscribed my name this 20th (lay of November. 1906.
